Abstract:
Objective:To explore the predictive value of helper T cell(Th)immune response indicators for asthma control in children with cough variant asthma(CVA)and its relationship with the risk of recurrence.Methods:A total of 112 children with CVA in Hengshui City People's Hospital from August 2020 to August 2021 were selected,all received conventional western medicine treat-ment,and were divided into well-controlled group(n=85)and poorly-controlled group(n=27)according to their asthma control status after 4 weeks of treatment.compare the general data,pulmonary function indexes before treatment[forced expiratory volume in 1 se-cond(FEV1),FEV1/forced vital capacity(FVC)],Th immune response indexes(Th1/Th2,IL-2,IFN-γ,IL-4,IL-10)levels,ana-lyze the correlation between Th immune response indicators and pulmonary function indicators,and predict the value of asthma control in children with CVA.After 6 months of follow-up,the recurrence situation in the well-controlled group was counted,the Th immune response indexes before treatment were compared between the children with recurrence and those without recurrence,and the relation-ship between Th immune response indexes and recurrence were analyzed.Results:Before treatment,the levels of FEV1,FEV1/FVC,Th1/Th2,IL-2 and IFN-γ in the poor control group were lower than those in the well-controlled group,and the levels of IL-4 and IL-10 were higher than those in the well-controlled group(P<0.05).Th1/Th2,IL-2,IFN-γ levels were positively correlated with FEV1,FEV1/FVC before treatment in children with CVA,and IL-4,IL-10 levels were negatively correlated with FEV1,FEV1/FVC(P<0.05);the areas under the curve(AUC)of Th1/Th2,IL-2,IFN-γ,IL-4 and IL-10 levels before treatment for predicting poor asthma control in children with CVA were all>0.7,and the combined predicted AUC(0.933)was the largest;before treatment,the levels of Th1/Th2,IL-2 and IFN-γ in the relapsed children in the group were lower than those of the non-relapsed children,and the levels of IL-4 and IL-10 were higher than those of the non-relapsed children(P<0.05);The levels of Th1/Th2,IL-2,and IFN-γ before treat-ment were negatively correlated with CVA recurrence,while IL-4 and IL-10 levels were positively correlated with CVA recurrence(P<0.05).Conclusion:Th immune response index has a certain value in predicting asthma control in children with CVA,and is closely related to the recurrence of CVA.
